The Nature of the Beast

Using Human Beings as Laboratory Animals

The true nature of the experiment had to be kept from the subjects to ensure their cooperation. The sharecroppers' grossly disadvantaged lot in life made them easy to manipulate. Pleased at the prospect of free medical care—almost none of them had ever seen a doctor before—these unsophisticated and trusting men became the pawns in what James Jones, author of the excellent history on the subject, Bad Blood, identified as “the longest nontherapeutic experiment on human beings in medical history.”

The study was meant to discover how syphilis affected blacks as opposed to whites—the theory being that whites experienced more neurological complications from syphilis whereas blacks were more susceptible to cardiovascular damage. How this knowledge would have changed clinical treatment of syphilis is uncertain. Although the PHS touted the study as one of great scientific merit, from the outset its actual benefits were hazy. It took almost forty years before someone involved in the study took a hard and honest look at the end results, reporting that “nothing learned will prevent, find, or cure a single case of infectious syphilis or bring us closer to our basic mission of controlling venereal disease in the United States.” When the experiment was brought to the attention of the media in 1972, news anchor Harry Reasoner described it as an experiment that “used human beings as laboratory animals in a long and inefficient study of how long it takes syphilis to kill someone.”
A Heavy Price in the Name of Bad Science

By the end of the experiment, 28 of the men had died directly of syphilis, 100 were dead of related complications, 40 of their wives had been infected, and 19 of their children had been born with congenital syphilis. How had these men been induced to endure a fatal disease in the name of science? To persuade the community to support the experiment, one of the original doctors admitted it “was necessary to carry on this study under the guise of a demonstration and provide treatment.” At first, the men were prescribed the syphilis remedies of the day—bismuth, neoarsphenamine, and mercury—but in such small amounts that only 3 percent showed any improvement. These token doses of medicine were good public relations and did not interfere with the true aims of the study. Eventually, all syphilis treatment was replaced with “pink medicine”—aspirin. To ensure that the men would show up for a painful and potentially dangerous spinal tap, the PHS doctors misled them with a letter full of promotional hype: “Last Chance for Special Free Treatment.” The fact that autopsies would eventually be required was also concealed. As a doctor explained, “If the colored population becomes aware that accepting free hospital care means a post-mortem, every darky will leave Macon County…” Even the Surgeon General of the United States participated in enticing the men to remain in the experiment, sending them certificates of appreciation after 25 years in the study.
Following Doctors' Orders

It takes little imagination to ascribe racist attitudes to the white government officials who ran the experiment, but what can one make of the numerous African Americans who collaborated with them? The experiment's name comes from the Tuskegee Institute, the black university founded by Booker T. Washington. Its affiliated hospital lent the PHS its medical facilities for the study, and other predominantly black institutions as well as local black doctors also participated. A black nurse, Eunice Rivers, was a central figure in the experiment for most of its forty years. The promise of recognition by a prestigious government agency may have obscured the troubling aspects of the study for some. A Tuskegee doctor, for example, praised “the educational advantages offered our interns and nurses as well as the added standing it will give the hospital.” Nurse Rivers explained her role as one of passive obedience: “we were taught that we never diagnosed, we never prescribed; we followed the doctor's instructions!” It is clear that the men in the experiment trusted her and that she sincerely cared about their well-being, but her unquestioning submission to authority eclipsed her moral judgment. Even after the experiment was exposed to public scrutiny, she genuinely felt nothing ethical had been amiss.
